Firefox unable to connect to webpages

Hi,
I am running Firefox 7.0.1 on Win7x64. Many times lately Firefox is unable to connect to webpages. It just hangs there saying "connecting" with the spinning ball on the tab, but nothing happens. No error message, no nothing.
I know it is not a problem with the Firewall. I have tried in Safe Mode and have the same problem. I know it is not an internet connection issue as all other browsers work fine. I have also uninstalled and reinstalled firefox, to no effect.
This problem generally manifests itself a minute or two after opening Firefox.
Please help, thanks

Try the solution in this help page. It worked for me great.

Firefox unable to connect

I have followed every single step in the article. I have installed and re-installed firefox, cleaned my cache, run every malware program, even restored a former version of firefox and run a system restore on my computer from before the problem occured. This morning my computer powered off without warning and when I rebooted, firefox would not work. I can connect to explorer and my remote desktop at work, so I know the internet connection works (even though I have still powered off and repowered my routers).

Since recent download of Firefox, "unable to connect"; Perhaps an older version will work; checked my firewall to allow, etc.; I'm connecting to you through Safari

I've been using Firefox until a recent download and now it won't connect. Perhaps an older version will work; checked my firewall to allow, etc.; I'm connecting to you through Safari; For some reason Internet Explorer is also not connecting. My computer uses Vista.

Hello Michael.
Hopefully this support article is what you need:
https://support.mozilla.com/en-US/kb/Firefox+will+not+start
In any case, it's possible that you are having a problem with some Firefox add-on that is hindering your Firefox's normal behavior. Have you tried disabling all add-ons (just to check), to see if Firefox goes back to normal?
Whenever you have a problem with Firefox, whatever it is, you should make sure it's not caused by one (or more than one) of your installed add-ons, be it an extension, a theme or a plugin. To do that easily and cleanly, run Firefox in [http://support.mozilla.com/en-US/kb/Safe+Mode safe mode] (don't forget to select ''Disable all add-ons'' when you start safe mode). If the problem disappears, you know it's from an add-on. Disable them all in normal mode, and enable them one at a time until you find the source of the problem. See [http://support.mozilla.com/en-US/kb/Troubleshooting+extensions+and+themes this article] for information about troubleshooting extensions and themes and [https://support.mozilla.com/en-US/kb/Troubleshooting+plugins this one] for plugins.
If you need support for one of your add-ons, you'll have to contact its author.
If the problem is not disappears when all add-ons are disabled, please tell me, so we can work from there. Please have no fear of following my instructions to the line, as all can be easily undone.
Also, if you want to use an older version of Firefox, please use Firefox 3.5.11. Only versions 3.5.11 and 3.6.8 are supported, and both contain all the latest security fixes. Using any other version is unsafe and not recommended.

Firefox unable to connect: bookmarked or previously visited websites connect, and some others, but new links or even pasted or typed in addresses don't, mac os10.5

For some reason, since this morning, any bookmarked or previously visited website works, and some others But new links or even pasted or typed in addresses don't. Must.figure.this.out! I don't have extra firewalls/security other than the standard mac ones and have restarted the computer and also rebooted all devices. Operation is safe mode has same results. Cleared cache and cookies.
Any ideas?
Thanks!
Brian

Firefox unable to connect after update!

I performed the Firefox upgrade to 4.0.1 today and now Firefox and IE8 won't connect to internet. Safari is able to connect as well as 2 other computers so I know the internet is working. Also IM programs work pointing to the internet working.
I tried removing Firefox and IE still wouldn't connect, I then tried to reinstall to Firefox 3.6.17 and it completed, but it won't open.

A possible cause is security software (firewall) that blocks or restricts Firefox without informing you about that, possibly after detecting changes (update) to the Firefox program.
Remove all rules for Firefox from the permissions list in the firewall and let your firewall ask again for permission to get full unrestricted access to internet for Firefox.

Unable to connect

If you are unable to load any pages, check your computer's network connection.

Contact the developer's support facility, same as with any other software that Apple didn't make.

Updated firefox, now I am unable to connect to the internet via mozilla but other browsers still work

When mozilla asked my for an update several months ago I chose to skip the install and wait. Did the install soon after and firefox stopped working even though my connection to the internet is fine. I uninstalled mozilla firefox, used another browser to access the mozilla website to reinstall firefox. This fixed my problem and firefox was working again, until another update came along. This time attempting to uninstall and reinstall did nothing. Once again I am left using another browser to use the support forum and firefox is not working. Please help!!

That is an indication that a firewall is blocking the new version of Firefox. For details see [[Firefox cannot load websites but other programs can]].

I am able to connect to the internet using internet explorer, but when I try to connect through mozilla firefox it says 'it is unable to establish a connection to the server." why?

I can establish internet connection through internet explorer using a router at my house, but whenever I attempt to connect using firefox, it says it is unable to connect.

A possible cause is security software (firewall) that blocks or restricts Firefox without informing you about that, possibly after detecting changes (update) to the Firefox program.
Remove all rules for Firefox from the permissions list in the firewall and let your firewall ask again for permission to get full unrestricted access to internet for Firefox and the plugin-container process.

My firefox won't work; It says "unable to connect" and I have tried all of the tips for troubleshooting and it still wont' work.

Firefox opens up with an "unable to connect" message; it also says it cannot establish a connection to the server with these three bullets: 1) The site could be temporarily unavailable or too busy. Try again in a few moments.
2) If you are unable to load any pages, check your computer's network connection.
3) If your computer or network is protected by a firewall or proxy, make sure that Firefox is permitted to access the Web.
I have tried to do all of the tips that you have on your website for troubleshooting and nothing seems to work. I know it is not my Internet connection because my roommates can get on Firefox without a problem and my Internet Explorer opens just fine.

If your iPad is defective and is still under warranty, you can take it to an Apple Authorized Repair Center and get it fixed. If you are worried about a defective replacement, then a repair may be a better way to go. <Apple Authorized Repair Centers>
Personally, I would prefer getting a replacement. You read about many defects here in this forum, but they only represent a tiny percentage of all iPads sold.
